ELLIOTT COMPANY, OF PITTSBURGH, PENNSYLVANIA, A CORPORATION OF PENN-SYLVANIA.

TURBINE.

Application filed February 18, 1916.

To all whom it may concern:

Be it known that I, ELMER E. Henna, a citizen of the United States,residing at Springfield, in the county of Clark and State of Ohio, haveinvented certain new and useful Improvements in Turbines, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

My invention relates to turbines and more particularly to a turbineadapted to travel through a tube with a cleaner, although 1t may be usedfor other purposes.

The object of my invention is to provide a simple, strong, durable andefficient turbine that will stand the severe shocks and jars incident toits use and can be readily assembled and easily taken apart forexamination and repairs.

It has been a common practice to construct the casing of turbines fortube cleaning by taking a bar of wrought steel and boring or hogging itout leaving an integral head or support for the front bearing. This isan expensive process in which there is a great waste of material. Toovercome this I have devised a construction in which I form the casingfrom an ordinary section of tubing, preferably the well known seamlessShelby tubing. This is very much less expensive than hogging it out froma solid piece.

A further object is to provide a removable front head and bearing soconstructed and arranged that they will not jar loose and having meansto hold the discharge openings through the respective parts inalinement.

IVith these and other objects in view my invention consists of theconstructions and combinations hereinafter mentioned and set forth inthe claims.

In the drawings which form a part of this specification Figure 1 is alongitudinal section of a turbine embodying my invention, taken on theline 11 of Fig. 3. Fig. 2 is a longitudinal section taken on the line2-2 of Fig. 3, and Figs. 3 and 4 are crosssections on the lines 33 and41 of Fig. 1 respectively.

Like numerals represent in the several views.

In the drawings 1 represents a tubular casing of uniform bore throughoutits the same parts length and open at its respective ends. It

may be formed from a section of ordinary tubing but I preferably employfor the purpose the well known Shelby seamless tubing. Within thetubular casing and intermediate of its ends an annular recess is cutinto which a ring or short section of tubing is expanded forming a stop2 as shown in Figs. 1 and 2. A rear bearing member 3 is seated againstthe front side of said stop and is preferably provided with a bushing 4.A front bearing member 5 preferably provided with a bushing 6 is seatedagainst the front end of a cylinder 7 the other end of said cylinderbeing seated against the rear bearing member forming a spacer betweensaid bearing members.

A turbine wheel 8 having buckets 9 and a central hub 10 and wearingplate 11 is screwthreaded to a shaft 12 against a shoulder 13 within thecylinder 7 Said shaft is journaled in the front and rear bearings,extends beyond the front end of the casing and is screw-threaded at 14cfor the attachment of the toolto be driven.

A thrust bearing is provided between the turbine wheel and front bearingmember and may be of any suitable form but I preferably employ ananti-friction bearing having two disks 15 each having oppositelydisposed hemispherical recesses opening through the outer walls so thatwhen the disks are riveted together by rivets 16 with balls 17 in saidrecesses the balls will project slightly beyond the outside walls ofsaid disks and contact with the wear plate 11 of the wheel and a likewear plate 18 seated in the front bearing member. The disks 15 form aholding member for the balls that permanently keep the balls in assembled position so that when the turbine is taken apart they will notdrop out and be lost. A plug 19 in the rear bearing member is removableso that the bushing in said bearing may be easily driven out.

A supply head 20 having the end of'a A discharge head 24 having acentral tapered opening 25 is screw-threaded into the opposite end ofthe casing, said tapered opening contacting a corresponding taper of thefront bearing member 5 and acting as a wedge to securely tighten andhold said member, as well as the cylinder 7 and rear bearing member 3 inthe casing against said stop. Discharge openings 26 through the frontbearing member 5 and through the discharge head 2& are provided and heldin alinement by dowelpins 27 seated in oppositely disposed openings inthe respective parts. The combined length of the oppositely disposedopenings is greater than the length of the pin and the diameter of theopening in the bearing member is slightly greater than the diameter ofthe pin so that in screwing the head into the casing against the bearingmember there is sufiicient play to insure the wodging or tightening ofthe parts in the casing against the stop.

Having thus described my invention I claim 1. In a turbine, a tubularcasing open at its respective ends, an inwardly projecting stop securedto said casing intermediate of its ends, front and rear bearing membersand a cylinder between said members, said cylinder and members beingintroduced through one end of said casing with means to hold the sameagainst said stop, a supply head secured to the other end of said casingand a turbine wheel in said cylinder having a shaft journaled in saidbearing members, said supply head and rear bearing member being spacedapart by said stop and forming a chamber having inclined inlets throughsaid bearing member to direct the motive fluid to the buckets of saidwheel, substantially as described.

2. In a turbine, a tubular casing open at its respective ends, aninwardly projecting stop secured to said casing intermediate of itsends, front and rear bearing members and a cylinder between saidmembers, said cylinder and bearing members being introduced through oneend of said casing with means to hold same against said stop, a supplyhead secured to the other end of said casing, a turbine wheel in saidcylinder having a shaft journaled in said bearings and a thrust bearingbetween said wheel and front bearing member, said supply head and rearbearing member being spaced apart by said stop and forming a chamberhaving inclined inlets through said rear bearing member to direct themotive fluid to the buckets of said wheel, substantially as described.

3. In a turbine, a tubular casing open at its respective ends, aninwardly projecting stop secured to said casing intermediate of itsends, front and rear bearing members having removable bushings thereinand a cylinder between said members, said cylinder and bearing membersbeing introduced through one end of said casing with means to hold thesame against said step, a supply head secured to the other end of saidcasing, a turbine wheel in said cylinder having a shaft journaled insaid bushings and a ball thrust bearing between said wheel and frontbearing member, said supply head and rear bearing member being spacedapart by said stop and forming a chamber having inclined inlets throughsaid rear bearing member to direct the motive fluid to the buckets ofsaid wheel, substantially as described.

4. In a turbine, a casing having an open end, a journal bearing memberintroduced through said open end, a head screw-threaded to said casingagainst said member to tighten and hold it in place, said head andbearing member each having discharge openings and means engaging saidparts to hold said discharge openings in alinement, substantially asdescribed.

In a turbine, a casing having an open end, a journal bearing memberintroduced through said open end, means to limit the inward movement ofsaid member, said member being tapered toward its outer end, a headscrew-threaded to said casing and having a taper opening to engage thetaper of said member to tighten and. hold. the same in place, said headand bearing mem ber each having discharge openings and a dowel-pinarranged to engage said parts to hold said discharge openings inalinement, substantially as described.

6. In a turbine, a casing having an open front end, a cylinder in saidcasing, means to limit its rearward movement, a journal bearing memberintroduced through said open end and seated against said cylinder, saidjournal bearing member being tapered toward its outer end, a headscrew-threaded to said casing and having a tapered opening to engage thetaper of said member to tighten and hold the same in place against saidcylinder, said head and bearing member each having discharge openingsand a dowel-pin arranged to engage said parts to hold said dischargeopenings in alinement, substantially as described.

7. In a turbine, a tubular casing open at its respective ends, aninwardly projecting stop secured to said casing intermediate of itsends, front and rear bearing members and a cylinder between saidmembers, a head screw-threaded to one end of said casing and having acentral tapered opening to engage a taper of said front bearing memberto wedge same within the casing and tighten and hold said cylinder andbearing members against said stop, a supply head secured to the otherend of said casing, a turbine wheel in said cylinder having a shaftjournaled in said bearing members, said supply head and rear bearingmember being spaced apart by said stop and forming a chamber havinginclined inlets through said rear bearing member to direct the motivefluid to the buckets of said wheel, substantially as described.
